vertex array tutorials

I believe the heightmap demo''s on game tutorials uses vertex arrays for rendering. It''s not difficult though. Basically it''s:

//create the arrays

float VertexArray[64*3]; //array for 64 vertices (3 floats per vertex)

float TexArray[64*2]; //array for 64 vertex texCoords (2 coords per vertex)

//store some data in it

FillArraysWithData();
//tell OpenGL where to find the stuff

glVertexPointer(3, GL_FLOAT, 0, VertexArray); 
glTexCoordPointer(2, GL_FLOAT, 0, TexArray);
//tell OpenGL to render a 64 vertex triangle strip

glDrawArrays(GL_TRIANGLE_STRIP, 64);

This is just off the top of my head so you might want to check the OpenGL docs for the exact syntax.
